OIL-CAN AND FILLER.

SPECIFICATION forming part of Letters Patent No. 515,124, dated February 20, 1894.

Application filed July Z2, 1893. Serial No, 481,177. (No model.)

To a/ZZ whom t may concern:

Be it known that I, EDWIN W. LUCE, a citizen of the United States, residing at Meadville, in the county of Crawford and `Stateof Pennsylvania, have invented certain new and useful Improvements in Oil-Cans and Fillers; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In a patent granted to me February 4', 1890, No. 420,812, I have shown, described and claimed an oil can or other fluid reservoir provided with a pump for discharging the contents of the vessel, the pump being constructed and arranged to prevent the running over of the lamp or other receptacle to be illed by having the pipe which supplies air to the pump barrel arranged to have its outer end dip into the receiving vessel so that When the fluid rises in the receptacle to the height of the end of the air pipe it will be drawn back into the pump and reservoir through said pipe, thus eectually preventing the overflowing of the same.

The present invention has for its object to provide an improved form of pump for use in connection with the above apparatus; also to adapt the pump for use in illing the reservoir itself, or for emptying the contents of lamps and other receptacles into the said' reservoir.

The invention is illustrated in the accompanying drawings forming part of this specification.

Figure 1 is a top plan View of my improved oil can and filler. Fig. 2 is a vertical section on the line 22, Eig. l. Fig. 3 is a similar section on the line 3-3, Fig. I;` and Fig. 4 a detail perspective view of the can spout and its several connections.

Similar letters indicate like parts throughout the different views.

Referring to the drawings, A indicates a can or reservoir for oil or other liquid in the top of which is secured a pump barrel or cylinder B, in which works asolid piston C, having rigidly secured thereto a piston rod c, bent at a right angle at its upper end, as at c', and engaging an eye CZ carried by a pivoted handactuated lever D which is pivoted at its front mounted on the head of the can. In the bottom of the pump-cylinder B a valve chamber Eis formed, and in this chamber a ball or other suitable valve e is seated, said valve normally closing communication between the reservoir and the pump barrel by gravity. Depending from the bottom of the pump-cylinder and extending nearly to the bottom of the can is a pipe e through which the fluid is drawn up into the pump by the action of the piston. The pump-cylinder B is provided at or near itslopposite ends with valve chambers F, E', the ports of which are normally closed by ball or other suitable valves f, f', and said valve chambers are connected by means of tubes or pipes f2, f3, with a chest G, secured in fixed position to the top ofthe can. Said chest is provided with ports g, g', which are respectively in communication with the tubes or pipes f2, f3. H indicates a movable chest similar tothe chest Gand provided with ports h, h', with which ports spouts h2, h3 communicate. The chests G, H, have Hat faces where they come together and are provided witha central aperture h4 through which passes a bolt iti-by means of which said chests are united in such manner that the chest H maybe relatively turned to the chest G so as to cause the ports leading to the interior of the reservoir to register with those leading to the spouts h2, h3. The spouts h2, h3, may be made entirely separate and distinct throughout their length, but I prefer to have their ends terminate in a single spoutdivided into two channels by a separating partition h6, as shown in Fig. 2, and in either case the ends will be bent downward so as to facilitatetheir introduction into the mouth or opening of a lamp or other receptacle. The upper end of the cylinder B is also provided With an outlet pipe I communicating with the interior of the can and provided with a normally closed valve z' opening outward relatively to the pump cylinder and held in closed position by gravity. This valve permits the iuid which is drawn into the cylinder from the receiving vessel through the pipe f2 to be forced back into the body of the reservoir by the upward movement of the piston.

As thus far described, the purpose and function of the pump are the same as that shown IOC ` in my former patent.

The construction and method of operation are, however, different, the principal difference being that the pump shown herein is a combined lift and force pump, raising the fluid from the reservoir into the cylinder and forcing it therefrom into the receiving vessel through the discharge pipe, whereas the apparatus illustrated in the old patent operated to expel the fluid by the pressure of air forced into the reservoir above the contents by the pump.

For the purpose f adapting the pump for use in filling the reservoir itself, or for e'm ptying the contents of lamps and other vessels, I provide the following arrangement: At or near the bottom of the pump barrel one end of an open tube .I connects. The opposite end of this tube extends upwardly and preferably to the head of the can or reservoir.

The tube is provided with apertures j, which afford communication between the interior of the vessel and the bottom of the pump-cylinder; Fitted in 'said tube is a tightly fitting solid plunger K provided with a rod 7c extending up through the tube above the top of the can, the purpose of this plunger being to-open or close communication between the cylinder and the interiorv of the reservoirthrough. the pipe J.

The operation of the device is as follows: When a lamp or other vessell is to be filled, it is; placed underthe spout so that the latter projects down into the vessel to thev level at which itis desired to'ill the same. The piston C being at the bottom of the pump-cylinder and the plunger K being fixed in the pipe J below the opening j as shown in Fig. 2, upon raising the piston by means of its operating handle D the air above the piston will be forced out through the pipe I, opening the-valvez' and passing into the interior of the reservoirfA. Asy the piston rises, it will also lift up the fluid through the pipe e. During the upward movementof the piston C, the valves f, f', remain closed. The piston is now at the upper end of the cylinder, and, as it descends, the valves t' ande close, shutting off communication between the cylinder and the interior of the reservoir. The valves fand f meanwhile open, the former permitting air to enter above the piston through the spout h2 and pipe f2, and the latter allowing the iiuid beneath the piston to be forced outthrough the pipe f5 and spout h5 into the receiving vessel. This operation is repeated until the oil in the lamp orother receiving vessel rises and closes the lower end of the spout h3 against the ingress of air to the cylinder, when the continued operation ofthe pump merely pumps in and out of the lamp equal volumes at each stroke. To prevent the entrance of solid matter into the pump cylinder through the air pipe h2, I cover its end with Wire gauze, or similar material, as shown in Fig. 2.

For the purpose of filling the reservoir itself, or emptying a lamp or other vessel containing fluid, the plungerK is adj usted in the tube .I to a point above the apertures j, and the pump piston is operated in the same manner as before described. It results from this arrangement, that, upon the down stroke, the oil beneath the piston, seeking the path of least resistance, will pass into-the tubeJand out through the apertures j into the reservoir. As the piston descends again it draws up the oil through the spout h2 into the cylinder above the piston, the ends 'of the spout being dipped down to the bottom of the lamp. Upon the next upward stroke of the piston the oil above the same is forced VVout of the cylinder into the reservoir through the outlet I. During the upward stroke of the piston, air from the interior of the reservoir freely enters the cylinderthrough the tubeJ and no fluid is drawn up through the pipe e.

I wish it tobe understood that I do` not regard the invention herein as limi-ted toA the particular form of pump, or the specific-details of construction or arrangement-of the apparatus, as many variations of the same are obviously within the spirit and scopeof' the same.

Having thus described the invention, Awhat I claimV is l. The combination with a fiuid reservoir, of a pump for dischargingthe contentsthereof into a receiving vessel, saidpump comprisin g a cylinder, an inlet pipe extending down into the reservoir, a dischargepipe leading to the receiving vessel, an 'air inlet pipe leading from the receiving vessel back tothe pump cylinder, and an air-outlet between the cylinderl and the interior of the reservoir, substantially as described.
